The ACE D allele is significantly associated with essential hypertension (allelic OR=1.37; homozygote OR=1.79), particularly in Indian and European populations.
Is the ACE D allele associated with an increased risk of essential hypertension?
The ACE D allele is significantly associated with essential hypertension, particularly in Indian and European populations, highlighting a genetic predisposition that varies by ethnicity.

Background: Essential hypertension (EH) refers to elevated arterial blood pressure with unknown etiology, which becomes more prevalent with age. Although the D allele of the ACE (I/D) polymorphism has been linked to EH, this association is not consistent across global populations. This systematic review and meta-analysis examined the relationship between the ACE (I/D) polymorphism and EH in diverse populations to determine the comparability of effect sizes and explore potential implications for public health planning. Methods: Case–control and cohort studies published in the last 20 years were reviewed from the main databases (PubMed, Scopus and Embase) using specific inclusion and exclusion criteria. Genotype data were used in meta-analyses using different genetic models. Results: Twenty-two studies with 7690 participants (3886 cases and 3804 controls) were included. Significant associations were observed between the ACE D allele and EH across allelic (OR = 1.37, 95% CI: 1.14–1.63), recessive (OR = 1.61, 95% CI: 1.21–2.13), dominant (OR = 1.37, 95% CI: 1.13–1.67), and homozygote (OR = 1.79, 95% CI: 1.31–2.45) models. Subgroup analyses showed significant associations in Indian and European populations, while African, Middle Eastern and Hispanic groups showed no statistically significant associations. Conclusions: The findings support a significant association between the ACE D allele and EH in several populations, though associations vary by ethnicity.
